Vehicle window glass and vehicle

Abstract

Vehicle window glass is provided. The vehicle window glass includes outer glass, inner glass, and an interlayer connected between the outer glass and the inner glass. The outer glass has a first tempered region and a second tempered region. The first tempered region is connected to the second tempered region. A surface stress of the first tempered region is greater than a surface stress of the second tempered region. A vehicle is further provided.

         2 . The vehicle window glass of  claim 1 , wherein the first tempered region is disposed around the second tempered region. 
     
     
         3 . The vehicle window glass of  claim 1 , wherein the first tempered region is disposed at at least one side of the second tempered region. 
     
     
         4 . The vehicle window glass of  claim 1 , wherein an area of the second tempered region accounts for 10%-90% of a total area of the vehicle window glass. 
     
     
         5 . The vehicle window glass of  claim 4 , wherein the inner glass has a thickness less than or equal to 1.2 mm. 
     
     
         6 . The vehicle window glass of  claim 5 , wherein the surface stress of the outer glass in the first tempered region is greater than or equal to 90 megapascal (MPa). 
     
     
         7 . The vehicle window glass of  claim 6 , wherein the surface stress of the outer glass in the second tempered region ranges from 20 MPa to 70 MPa. 
     
     
         8 . The vehicle window glass of  claim 7 , wherein the outer glass has a thickness ranging from 3 mm to 5 mm. 
     
     
         9 . The vehicle window glass of  claim 8 , wherein the inner glass is aluminosilicate glass. 
     
     
         10 . The vehicle window glass of  claim 9 , wherein the inner glass has a surface stress ranging from 450 MPa to 850 MPa. 
     
     
         11 . The vehicle window glass of  claim 10 , wherein the inner glass has a stress layer with a depth of 30 μm-70 μm. 
     
     
         12 . The vehicle window glass of  claim 1 , wherein the inner glass is chemically tempered glass. 
     
     
         13 . The vehicle window glass of  claim 1 , wherein the first tempered region comprises a first tempered edge-region and a first tempered fixed-region connected to the first tempered edge-region, the first tempered edge-region is located at a periphery of the second tempered region, and the first tempered fixed-region and the first tempered edge-region cooperatively surround the second tempered region. 
     
     
         14 . The vehicle window glass of  claim 13 , wherein in a direction from an edge of the vehicle window glass to a center of the vehicle window glass, a width of the first tempered edge-region ranges from 50 mm to 100 mm. 
     
     
         15 . A vehicle, comprising a vehicle body and vehicle window glass, wherein the vehicle window glass comprises outer glass, inner glass, and an interlayer connected between the outer glass and the inner glass, the outer glass has a first tempered region and a second tempered region, the first tempered region is connected to the second tempered region, and a surface stress of the first tempered region is greater than a surface stress of the second tempered region; and wherein the vehicle window glass is connected to the vehicle body. 
     
     
         16 . The vehicle of  claim 15 , wherein the first tempered region is disposed around the second tempered region. 
     
     
         17 . The vehicle of  claim 15 , wherein the first tempered region is disposed at at least one side of the second tempered region. 
     
     
         18 . The vehicle of  claim 15 , wherein an area of the second tempered region accounts for 10%-90% of a total area of the vehicle window glass. 
     
     
         19 . The vehicle of  claim 18 , wherein the inner glass has a thickness less than or equal to 1.2 mm. 
     
     
         20 . The vehicle of  claim 19 , wherein the surface stress of the outer glass in the first tempered region is greater than or equal to 90 megapascal (MPa).
